I traded in my Cadillac Deville that had no problems with 112,000 miles (never one repair) for this SUV assuming that it would be more reliable since it was made by Mercedes- Benz. Was I wrong. After 55,000 miles I had to replace the drive shaft. Then the harmonic balancer went out and took everything else out with it, that cost 1200.00 and turned out to be a recall. M-B reimbursed me 200.00 of the 1200.00. I have also replaced the transmission, transfer case, rear shocks, front struts. I have put almost 10,000 in repairs in this vehicle. The only good I have to say is the safety. I was the first car rearended by a surburban in a 4 car pile up and neither myself or daughter was hurt.
Crash safety. Power. Bose speakers. Great in the snow.
Everything mechanical needs to be replaced. Back drink holders. Less rattling.
